Be it known that l, NILS H. ELNDERSONJ a I citizen of the United, -'tates, residing at Hartforch in the countyofHartfordand State/of Connecticut. have invented certain new and. useful Improvements in Type \Vriting- Machines, of Which the following is afl ll, clear, and exact descriptiom'such as I will enableothers skilled in the art to which it appertains'to make and iisethe-same.

This invention relates topaper feeding mechanism. for'-type\ vriting: machines. and

with re ard to 'thefino'iie specific features thereof, to paper clips particularly adapted One of the objects of theinvention; is to nroi'ide new andimproved means for feedv tobe used on machines of the front strike ing the paper-over the platen an'd'for maintaining the sheet in such position, that the twriting will be constantly in ,view of -tlhe operator. 3 7

Another object is th provide pap er feelding mechanism of the above character which I vencyof the same in part pointed out hereinafter.

1 The invention accordingly consistsin the features "of. const'ruc'tiO l-f combinations of elements and arrangement of parts which will be exemplified in the 'COEStIUCllOIl-llQIG- I i'nafte r- .-set forth. and the scope of the application of which will, be indicated in the .ustrate d one orthe various possible embodi- 10f av, improyed ,mecham nents ofmy'inyention, Figure l is a plan view sm; Fig. 2 is a front elei ation thereof Fig. is an end View taken will remore any irregularities or bulges in which will correctany tend- Inth-e acco npanying drawings. wherein'is v "on line "3-3, Fig. Fig.4 is'a similar View taken on line 4-45Fig.,2, the parts being shown indifferent-positions; Fig. 5 is a-planlview, upon in-enlarged scale; of'a' portion of the platen roll and the frnsto conical paper cliprolls; showing the manner 1n which they are; a lined'on the platen roll,

Similar reference characters refer to similar parts throughout the several views of the drawings. v i

.Referring now to the drawings, 1 and 2 respectively denote the side members of the platen frame, in which is. ]ournaled the shaft 3 of the platen roll 4. The platen is a thin strip of metal 5, having a plain front face fer THZGU'HIQ; the types, and a carved 'rear face which conforms to the contour of,

the platen roll and lies in Contact therewith said platen being extended between the end members 1 and 2 and fastened. thereto by screws 6. A paper table 7 is shown fixed in the platen frame and extending beneath the platen roll, the forward end thereof terminating substantially directly below the platen. Y

8 indicates one of the main paper feed rollers of the setithereof which is supported in the platen frame beneath the platen roll, said roll being carried by an arm 10 mounted upon a, rod 11 which extends longitudinally of the platen frame and is supported at its ends in the side members thereof.

12 and 13 respectively indicate arms which 'are mounted upon suitable bearings adja- .tion of one thereof will suflice.

cent the platen roll shaft and swing con centrlcally with. the central axis thereof. Between the outer ends of arms 12 and 13 is extended a rod or bar 14 which is formed of sheet metal bent into the shape shown in cross section in Figs. 3 and 1 of the drawings. Bar 14. which may he graduated, if desired. extends longitudinally of and parallel to the platen roll.

The carriers for the paper clip rolls and the paper fingers, best shown in Figs. 5 to 7 inclusive. are metal brackets 15 bent to conform to the shape of bar 14 and slide vided with a slot 20 for accommodating the paper clip rolls, and portions of the metal at either side of the finger are bent upward to form ears 21. Ears 21 are slotted at to receive the axle pin 23 which .carries the paper clip roll, said pin being held against turning by means of notches 24 formed therein which engage the walls of the shits 2:2.

Mounted to rotate upon pin 23 is a double flanged sleeve 25 carrying a paper clip roll 26. This roll is beveled as shown and the rolls of rackets 15 are so disposed thereon that the ads of the rolls having the smaller diameters face each other. the rolls being arranged in alinement as shown. The rolls of each of the brackets extend through the slots 20 of the paper finger and run on the platen roll. aswill be understood. lIounted upon pin 23 at either side of sleeve 25 which supports the frusto-conical paper clip roll are collars 27. These collars form bearing points for the ends of a bifurcated leaf spring 28 which is secured to the bracket by means of the rivet 16 and extends forward therefrom. Spring 28 operates to maintain the beveled paper clip roll in engagement with the platen roll.

Each of brackets 15 is provided with a finger piece 30. secured to'the brackets'by the rivet 16 and cur ed so as to fit partially about the finger, whereby the brackets may be easily slid in either direction upon the supporting bar 11.

Arms 12 and 13 which support bar 14 are provided with projecting ends'31 which enagewith stop pins 32 when bar 14 is swung to the position shown in Fig. 3 of'the draw ings. stop pins 33, being provided with which said arms engage when the bar is swung to the position shown in Fig. 4. Leaf springs 34 engage with arms 31 and hold them in engagement with one or the other set of stop pins.

clamped upon either end of bar 14 is a bracket 35 provided with a finger piece 36. Either ofthese finger pieces may be grasped by the hand of the operator when it is desired to swing the bar 14 and the devices carried thereby from or to either of the positions shown in'Figs. 3 and 4 of the drawings.

37 indicates a bracket formed of bent metal so as to fit about bar 14 and slide thereon and which may be placed upon said bar in any position between the brackets which carry the paper clip rolls. This bracket has swii'eled thereon a clip finger 3S, pivoted at 40 in the bearings 41, formed by two projectingbent-over ends of the bracket. said clip finger being adapted to be swung downward to engage with the platen roll. as shown in Fig. 11, or upward therefrom. as shown in Fig. 10, a spring portion 42 of bracket 37 engaging with either of two flat sides, 43 or 44, adjacent the pivotal pqint of the clip and operating to hold the same in either of said positions.

Having thus described the construction of this embodiment of my invention, the manner in which the same operates may now be explained. The normal position of the bar 14 which carries the paper clip roll brackets 15 is that shown in Fig. 3 of the drawings, in which position the paper finger 17 receives the advancing end of the paper as the same is fed underneath the platen roll and guides the same upwardly over the platen 5 and between the paper clip rolls 26 and the platen roll. When the platen roll is turned,

the frusto-conical faces of the paper clipsheet, but inasmuch as they are supported against bodily movements in brackets 15, the reaction of these rolls against the paper tends to move it outward under both of the rolls away from the center of the sheet. The

paper is therefore always maintained in engagement with the platen roll throughout its lateral extent. When it is desired to obtain access to the paper to make erasures,

menses rolls running over the paper upon the platen the paper.

roll andoccupying a position adjacent the "platen.

platen roll 1s thus exposed and erasures may The paper upon the top of the be readily'made in the original as well as in the carbon copies, It will be observed that inasmuch as bar 14: and the paper clip rolls carried thereby are mounted concentrically with the axis of the paper roll, the paper clip rolls will be maintained in engagement with the paper upon the platen roll, whatever position they'occupy thereon. When it is desired to write upon enrelops, the brackets 15 may be moved toward the center of the platen roll to engage the lateral edges of the envelops and the clip 38 may be swung down to engage the top edge thereof, where'- by the envelop is conveniently held in posi tion for writing,

It will accordingly be seen that l have provided mechanism well adapted to attain, among others, all the ends and objects above enumerated. Through the provision of the radially swinging arms which carry the supporting bar for the beveled paper clip rolls, saidbar may be swung to the position occu pied in Figs. 3' and 4: so that access may be had to the paper, and it is therefore unnecessary at any time to disengage the rolls from These rolls always being in engagement with the paper, operate to hold it firmly in, position when erasures are being made. .Anothcr advantage inherent in the invention resides in the fact that the paper maintained always in engagement with the platen roll through the provision of the beveled paper clip rolls.

As many changes could he made in the above construction and many. apparently widely different embodiments of this invention could he made without departing from the scope reef, it is intended that all matter COHiLiAZiEil in the above description. or shown in the accompanying drawings shall be interpreted as illustrative and not in a. limiting sense.
